Profile

Associate Professor (Botany, Ecology, Plant Conservation, Biosystematics). Research interests include plant biosystematics and biogeography (with a special interest in insular flora), plant conservation and management, threat classification systems, the cytogenetics and ecology of island endemic plants and ethnobotany. I also have an interest in Quaternary Earth Sciences. I have an M.Sc. (Hons) in Palaeoecology and Tephrochronostratigraphy from the University of Waikato, and a PhD in Plant Biosystematics from the University of Auckland. I am an Adjunct Professor of the Department of Natural Sciences, University of Sassari, Sardegna, Italy.

Prior to taking my current position I worked for the former DSIR Botany Division (1984-1985), Ministry of Agriculture & Fisheries in the Aquatic Plants Division (1989-1990) and Department of Conservation as a Research Scientist (1990-2017).

I have published over 170 papers in peer-reviewed literature, and 20 books - mostly on threatened plant conservation, management, biosystematics and island flora.
